Note: Some these failed to work for me in Firefox, but they all worked great in Chrome.
These shaders run entirely on the GPU, even the ones that have logic where the camera flies through the scene.
Some of them really gave my GPU a workout. With an aggressive fan curve, the core temp stayed under 70c, but it was exhausting heat like a mini blast furnace.
Haven't seen all the demos yet but here are some favorites so far:
(Note, the numeric 0.5/1/2/4/8 pulldown menu to the right of the "hide code" button seems to change the shader resolution, the higher the number, the lower the resolution factor... Generally for best results make the number as low as possible without compromising framerate.)
An on-GPU raytracer: http://glsl.heroku.com/e#12290.0 (looks especially nice at 0.5 resolution, though my GPU can't quite hack it at 60Hz with 0.5 resolution at a full 1920x1080... gets slightly choppy in fullscreen... otherwise, glassy smooth)
Just fer fun, hastily put together a Halloween Haunted House Dungeon track yesterday evening to hopefully creep out the Trick-or-Treaters tonight (made using ACID pro 7 and samples from the Sony Pictures Sound Effects Series library)
"A remarkable cap of a fifty year intellectual journey."
Lawrence Krauss appears briefly in the following video, in a Q&A session, giving the most clear and concise explanation I've yet heard geared at a general audience for why the Higgs field was proposed (leading to the search for the Higgs boson.)
Here's a more detailed 50 minute treatment of the above, beginning with Galileo and Faraday's discoveries and building up through Maxwell, Einstein, Feynman, etc. to explain layer by layer how theory confirmed by experiment drove physicists eventually to propose the Higgs field:
Just added a GOTO ZIGBOT server running Zigock bots and FFA maps.
mymap is enabled, with pretty much all the FFA maps we have routes for. (In order to add additional maps, route files need to be created for the bots.)
It's taken a few weekends of hacking to fix various glitches and stability issues with the mod. Hopefully it's stable enough now. (Still has to use a special r1q2 mode to completely reload the game DLL on map change to prevent it crashing.)
NOTE 1: I'm aware the bots do goofy things (spazzing out on ledges, for instance.) At this point it is what it is.
NOTE 2: Currently 7 bots are spawned in regardless of number of players or map size. In the future I'd like to make the number of bots vary based on map size, and also adjust based on number of players.
Most conventional nuclear reactors – in the US at least – are light-water reactors, but this design has a number of disadvantages. The reactors only use about 3 per cent of the potential energy stored in the uranium pellets that power them, and the resultant waste still contains enough energy to be radioactive for hundreds of thousands of years. The average US plant produces 20 tons of such waste a year.
They also suffer from safety problems, since an external power source is required to cool the reaction chamber and to shut down the plant if necessary. It was the failure of these power systems (owing to the tsunami cutting both power to the plant and swamping the backup generators) that caused Fukushima's reactor problems.
The WAMSR takes "waste" fuel pellets and dissolves them in molten salt. The fluid is then pumped into a graphite core to induce a reaction and generate heat, which is extracted via a heat exchanger and used to drive steam turbines and generate power.
The design is much more fuel-efficient than light-water reactors – using 98 per cent of the potential energy in uranium pellets – and a WAMSR unit would produce just three kilos of waste a year that would be radioactive for only hundreds of years rather than hundreds of thousands.
With around 270,000 tons of nuclear waste available worldwide, the reactors would be enough to supply all the world's projected energy needs for the next 70 years. As a side benefit, this could also reduce nuclear proliferation since countries would no longer have to manufacturer nuclear fuel.
As a safety feature, WAMSR's liquid-fuel pipes are connected to a drain plug of salt that has been frozen solid. If humans aren't around and the power to the plant fails, the plug melts and the nuclear fuel drains into a holding tanks, cools, and solidifies over the space of a few days.
It's also supposed to be less expensive to build than prior reactors.
If this thing really works, what a freakin win-win.
sponge from id Software is organizing a Q2 FFA event for Q2's 15th anniversary, scheduled for tomorrow night, Friday Dec 7th, 8PM central time, on the TS500 server!
Currently the plan is just a big FFA game. The DM maps are in the rotation by default, but if lots of folks show up we can switch to the *64 maps, or perhaps some of the more well-known single player maps.
Received the following info this evening from the hosting provider:

**EMERGENCY NOTIFICATION**
Please be advised that Internap's LGA11 facility is experiencing significant flooding in the sub-basement of the 75 Broad Street building as a result of Hurricane Sandy. The flooding has submerged and destroyed the site's diesel pumps and is preventing fuel from being pumped to the generators on the mezzanine level. The available fuel reserves on the mezzanine level are estimated to support customer loads for approximately 5-7 hours. Once this fuel supply has been exhausted the generator will no longer be able to sustain operation and critical customer power loads will be lost. We urge all Internap customers to take necessary remote action, if shutting down equipment in a more graceful fashion is possible before the outage occurs.
The building itself is being evacuated and no remote hands support will be available to assist in any equipment shutdown. Life safety is our number one priority and we are making plans to completely exit the facility. No customer access to the building is possible at this time either. Due to the evacuation, Internap will not be able to provide any exact updates on when the fuel will be exhausted and critical customers loads lost, but as noted, we believe it will take place in approximately 5-7 hours from now.
So: east.tastyspleen.net has been backed up and shut down cleanly for the duration.
GOTO JUMP has been relocated to Dallas for the time being (all map times should be intact.)

It's weird that while we have people killing one another over a concept, others of us are free to contemplate the nuance level at which denigration of a particualar concept becomes acceptable.
(Or, perhaps likewise, the rejection of the idea that denigration of a concept warrants more than stern letters to the editor.)
If that's true, then my hypothesis is
<|iR|DEATH_TO_ISLAM>
is morally equivalent to
<|iR|DEATH_TO_ABRAHAMIC_MONOTHEISM>
is morally equivalent to
<|iR|DEATH_TO_CAPATILAISM>
is morally equivalent to
<|iR|DEATH_TO_ASTROLOGY>
is morally equivalent to
<|iR|DEATH_TO_NEWTONIAN_PHYSICS>
is morally equivalent to
<|iR|DEATH_TO_THE_PHLOGISTON_THEORY>
all of which is an obvious play on the already-existing
<|iR|DEATH_TO_AMERICA>
etc.
e.g. these are all *concepts*
none of which target *people* but *ideas*.
IDEAS ARE ALWAYS UP FOR DEBATE
right?
N.B. standards for debate may require evidence, etc.; but nobody gets killed for not providing evidence: just ridiculed or kindly turned away
We'll likely be upgrading the forum software soon.
We've been inundated with spammers signing up to the forum lately; often more than 50 per day I need to wade through and delete, while hopefully not rejecting any legit sign-ups.
The later forum software versions support plug-ins that, with a little customization, can auto-reject the majority of the spammers, and make the ones that aren't auto-detected still easy to distinguish from legit registrations by the admin. (I deal with this on other websites and it's worked really well.)
When the forum upgrade happens, it will initially probably revert to being bare-bones (no shoutbox, no "quake sites & friends" links at the top, etc.) I'll need to hack the various customizations back in afterward.
I might have posted a link to this on another thread a few weeks ago, but anyway...
If the rest of the galaxies are anything like our local neighborhood, there are likely over 10,000,000,000,000,000,000,000 planets in the observable universe.

You only changed it to be in decimal, you did not change the id at all. Is there some reason why you can not change it? You said there was a reserved range of ids that could be used, perhaps just pick another one? What is the valid range that can be used here?
And with age comes experience. You learn how to deal with children who need to be told stories
Ahah. Well ya got me! I thought you were serious with all the Jesus stuff.
Quadz, I see you're not a man of faith.
That's true. I do think extraordinary claims require extraordinary evidence.
From my point of view, faith is not a virtue. Faith is an abdication of reason and a suppression of one's critical faculties of the kind that allows people to believe things on bad evidence, such as the claims of noted fraudster Joseph Smith about seer stones and golden plates and the Garden of Eden being located in western Missouri.
Smith's claims should be transparently obvious as a con job to any thinking person - except anyone taking them on faith.
Faith also supports the belief that the Jesus story is special, when instead it fits neatly into the traditional mythical hero archetype:

The hero scale from Lord Raglan's The Hero (1936)
1: The Hero's mother is a royal virgin. 2: His father is a king and 3: often a near relative of his mother, but 4: the circumstances of his conception are unusual, and 5: he is also reputed to be the son of a god. 6: At birth an attempt is made, usually by his father or his maternal grandfather, to kill him, but 7: He his spirited away, and 8: reared by foster-parents in a far country. 9: We are told nothing of his childhood, but 10: on reaching manhood he returns or goes to his future kingdom. 11: After a victory over the king and/or a giant, dragon, or wild beast, 12: he marries a princess, often the daughter of his predecessor, and 13: becomes king. 14: For a time he reigns uneventfully, and 15: prescribes laws, but 16: later he loses favor with the gods and/or his people, and 17: is driven from the throne and city, after which 18: He meets with a mysterious death, 19: often at the top of a hill. 20: His children, if any, do not succeed him. 21: His body is not buried, but nevertheless 22: he has one or more holy sepulchres.
